Dyna-Fresh AQC Air Quality Control Center

When tightly insulated homes have windows and doors shut, stale air is sealed in and fresh air is sealed out. Fresh air provides a healthier home and work environment. The key to eliminating moisture, bacteria, carbon monoxide and household odors is bringing fresh air indoors. The Dyna-Fresh Air Quality Control System brings outdoor air inside to make a more comfortable and healthy environment. The key component is a control panel which draws air into the home or workplace at pre-determined intervals with a 24 volt timer or manual override for continuous fresh air flow. The fresh air is drawn in through a motorized round damper. This fresh air is mixed with the indoor air already inside the heating / cooling system. The mixture is now circulated through the ductwork while stale air is vented out through an existing ventilation (such as a bathroom exhaust fan).

• The Dyna-Fresh AQC has a programmable (in 15 minute intervals) 24 hour timer which is wired to control a DuroZone Spring-Return Damper (110 volt or 24 volt), an exhaust fan, and the air handler fan. Once the timer has been programmed, a call from the Dyna-Fresh AQC for fresh air will.

The house has natural gas heating and A/C. The furnace is an American Standard Freedom 80. The Honeywell thermostat is set for auto system and fan. There is a timer control for the fresh air intake (a Duro Dyne AQC-1) which is currently set to run nearly continuously, except for a few randomly spaced 15 or 30 minute intervals.

CONSTANT ENERGY CONSERVATION emphasis and local building code changes over the past several years have resulted in efforts to make buildings and homes more weather tight and draft free. While these efforts have been successful, eliminating outside air leakage has created another potential problem; air quality of the interior atmosphere.

Many provincial and local governments have become concerned that the relatively stagnant indoor air is showing increasing levels of carbon monoxide and carbon dioxide. Many provinces have required periodic introduction of outdoor air into the indoor environment. The Dyna-Fresh Air Quality Control Center coupled with a model NSPRD024 or SPRD110 Spring Return Damper was designed for this purpose.

1. Fresh air is drawn in from the outside and mixed with return air to be distributed by the air handling equipment.
2. The Dyna-Fresh AQC Control Panel coordinates the blower, exhaust fan and damper to introduce fresh air and remove stale air at user selectable 15 minute intervals.
3. Stale air is exhausted by the independent exhaust fan.

• Open the Spring Return Damper to allow fresh air into the return duct
• Turn on the air handler fan to distribute the fresh air into the home
• Activate an exhaust fan to remove the stale air in the home or office
